Description

Skin beauty device using RF needle

The present invention relates to a skin beauty device using an RF needle, and more specifically, to a skin beauty device using an RF needle configured to apply a thermal effect to skin tissue by inserting RF energy into the skin by moving the needle back and forth.

Unless otherwise indicated herein, the materials described in this section are not prior art to the claims of this application and their inclusion in this section is not an admission that they are prior art.

Recently, technologies that improve skin using various energy sources are being widely applied.

Currently, research is actively being conducted on skin treatment devices that utilize laser beams, ultrasound, and RF high-frequency energy.

This technology supplies energy to the skin, generates heat through the movement of molecules that make up the skin tissue, and increases the temperature inside the skin through the heat, which reorganizes the collagen layer to achieve therapeutic effects such as skin elasticity and improvement of wrinkles.

In the case of conventional RF needle equipment, there was a problem in that the equipment contact surface did not make accurate contact with the skin due to the curvature of the skin during the procedure, so many needles were not inserted into the skin layer to the appropriate depth, and some needles were not inserted or were inserted shallowly.

The present invention aims to provide a skin beauty device using an RF needle, which generates a suction force in an area in contact with the skin, pulls the skin, and inserts the RF needle so that the needle can be accurately inserted into the skin.

According to one embodiment of the present invention, a skin beauty device comprises: a handpiece; a needle assembly configured to be detachably attached to a tip end of the handpiece, capable of being driven forward and backward by a motor and including a needle to be inserted into skin; an RF generator configured to apply RF energy to the needle inserted into the skin in the needle assembly; a skin contact portion formed at a tip end of the needle assembly; and a suction tube connected from one side of the needle assembly to one side of the handpiece, and a vacuum pressure forming portion configured to form a vacuum pressure to pull skin in contact with the skin contact portion.

In addition, the vacuum pressure formed in the vacuum pressure forming unit can be transmitted toward the skin in contact with the skin contact unit to form a shock wave.

In addition, a guide tube may be further included to guide air sucked through the suction tube to be discharged into a space formed inside the handpiece.

In addition, the device further includes a control unit that controls the needle assembly, the RF generation unit, and the vacuum pressure forming unit, and the control unit can control the needle to advance through the motor while pulling the skin in contact with the skin contact unit through the vacuum pressure forming unit, and to generate RF energy in the RF generation unit and apply it to the needle.

In addition, the skin contact portion is formed along the circumferential direction of the area where the plurality of needles are formed, and the control portion can control the needle to advance through the motor only when the skin is in contact with the entire area of the skin contact portion when vacuum pressure is formed in the skin contact portion from the vacuum pressure forming portion, and to apply RF energy to the needle from the RF generating portion.

In addition, the needle assembly may be configured such that a plurality of needles are spaced apart within a predetermined area with a certain rule, the skin contact portion is formed along the circumferential direction of the area where the plurality of needles are formed, and a vacuum pressure is formed in the vacuum pressure forming portion to pull the skin line in contact with the skin contact portion.

According to one embodiment of the present invention, a skin beauty device using an RF needle has the advantage that the needle can be accurately and densely inserted into the inner layer of the skin while the skin is pulled by a vacuum pressure forming unit.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

According to one embodiment of the present invention, a skin beauty device comprises a handpiece (100), a needle assembly (200) configured to be detachably attached to a tip of the handpiece (100), capable of being driven forward and backward by a motor (210) and including a needle to be inserted into the skin, an RF generator (not shown in the drawing) that applies RF energy to the needle inserted into the skin in the needle assembly (200), a skin contact portion (400) formed at a tip of the needle assembly (200), and a suction tube (510) connected from one side of the needle assembly (200) to one side of the handpiece (100), and a vacuum pressure forming portion (500) configured to form a vacuum pressure and pull the skin in contact with the skin contact portion (400).

The handpiece (100) above has a predetermined space formed inside, and may be formed in a shape that is extended long along the longitudinal direction so that a user using the device can easily grasp it. The handpiece (100) may be connected to the main body through a wire formed at the rear end thereof, and power may be supplied by the operation of the main body or the handpiece (100) may be operated by the control of the main body. However, the present invention is not limited thereto, and a control unit that controls all operations within the handpiece (100) without being connected to the main body may be installed.

The tip of the handpiece (100) may be configured to have a detachable needle assembly (200). The needle assembly (200) may have a predetermined space formed therein that can accommodate needles arranged with a predetermined rule. Here, the needles may be arranged regularly on a plate (220) that forms a predetermined area and fixes the needles with a plurality of needles. In one embodiment, n needles are arranged in each of the horizontal and vertical directions and densely arranged within a square, so that when the needles are moved back and forth toward the skin, a plurality of wounds in a square shape are generated on the surface that comes into contact with the skin.

In addition, a plurality of penetration holes (231) are formed corresponding to the positions of the needles so that the plurality of needles can penetrate and be inserted into the skin, and a needle case (230) that comes into contact with the skin when the needles are inserted into the skin may be included. The needle case (230) may be positioned substantially at the leading edge of the needle assembly (200), and when the needles advance while in contact with the skin, the needles can be inserted into the skin by passing through the penetration holes (231).

In the above-described needle structure, different AC signals having opposite polarities can be transmitted to adjacent needles. More specifically, when RF energy generated through the RF generation unit (300) is applied to the needles to generate a wound in the skin, each needle is configured in a bipolar manner so that high frequency flows out from a needle with a + electrode and moves to a needle with a - electrode at an adjacent location, thereby generating a wound in a certain area centered on the location where the needle is inserted and causing collagen production, thereby helping to improve the skin.

The above needle assembly (200) is configured to be driven forward and backward by a motor (210) connected to the rear end, and more precisely, the shaft (211) of the motor (210) is connected to the rear end of the plate (220) that fixes the needle in the needle assembly (200), and the plate (220) is driven forward and backward by the operation of the motor (210).

Next, the needle assembly (200) may include an RF generator that applies RF energy to a needle inserted into the skin. The RF generator may be formed in the handpiece (100) to generate an RF signal to apply RF energy to the needle, but is not limited thereto. RF energy generated from an external device may be received through a wire connected to the handpiece (100) and supplied to the needle. Here, a power switch (300) for controlling the operation of various components installed in the handpiece (100) may be formed on one side of the longitudinal center of the handpiece (100).

In addition, a skin contact portion (400) may be formed at the tip of the needle assembly (200). The skin contact portion (400) is formed as a portion that actually comes into contact with the skin surface when the needle assembly (200) is in close contact with the skin.

Preferably, the skin contact portion (400) may be formed along the area where the plurality of needles are formed, that is, the circumferential direction of the needle case (230). The needle case (230) also comes into contact with the skin, but does not come into complete contact with the skin during the entire period during which the needle is inserted while moving back and forth, and a gap is generated by a microscopic gap, so that vacuum pressure is formed in the relevant portion and the needle cannot be pulled. Accordingly, the skin contact portion (400) is formed along the circumferential direction of the needle case (230), and the vacuum pressure is generated through the vacuum pressure forming portion (500) described below, so that the circumference of the contacted skin is completely pulled, thereby preventing the phenomenon of the skin overlapping or being pushed, and allowing the needle to be inserted accurately into the desired skin layer.

Finally, the vacuum pressure forming unit (500) may include a suction pipe (510) connected from one side of the needle assembly (200) to one side of the handpiece (100) and configured to pull the skin in contact with the skin contact portion (400) by forming a vacuum pressure. The vacuum pressure forming unit (500) may be configured as a separate component installed in the handpiece (100) and may be largely configured with a vacuum pressure forming module (510) for forming a vacuum pressure, a suction pipe (520) interconnected to the needle assembly (200) and the vacuum pressure forming module (510) installed in the handpiece (100), and a guide pipe (530) for guiding the air sucked through the suction pipe (520) to be discharged into a space formed inside the handpiece (100).

The above vacuum pressure forming module (510) may be installed inside the handpiece (100), and more specifically, may be installed on one side of the inner circumferential direction of the handpiece (100) at a position adjacent to the needle assembly (200). A suction pipe (520) extending from the vacuum pressure forming module (510) may pass through one side of the handpiece (100) and extend to the side of the needle assembly (200). The suction pipe (520) extending to the side of the needle assembly (200) may have a predetermined diameter so that a connecting pipe (521) formed on the side of the needle assembly (200) may be inserted therein.

The above connecting pipe (521) is connected to the skin contact portion (400), more precisely, the skin contact portion (400) formed along the circumference of the needle case (230) through the needle assembly (200), so that when in contact with the skin, vacuum pressure is formed in the skin contact portion (400), thereby pulling the skin.

In addition, it is necessary to discharge the air sucked from the vacuum pressure forming module (510), and a guide tube (530) may be formed to guide the air to be discharged along the longitudinal direction from the inner surface of the handpiece (100).

In another embodiment, the vacuum pressure formed in the vacuum pressure forming unit (500) can be transmitted toward the skin in contact with the skin contact unit to form a shock wave.

When a vacuum pressure is formed and the skin is pulled as much as possible, the needle is inserted, which has the advantage of being able to be inserted accurately into the inner layer of the skin. However, when a large number of needles are inserted into the skin, damage to the skin tissue occurs, which causes pain. In order to alleviate this pain, when the vacuum pressure is formed at the skin contact portion (400), the intensity or cycle of the pressure can be controlled to induce the formation of a micro-shock before pulling the skin. Here, the shock is applied by applying air pressure, and when the intensity or cycle is set to the aforementioned intensity or cycle, the skin sensation is slowed down by the shock caused by it, and when the skin is pulled and the needle is inserted immediately afterwards, the pain caused by the wound can be reduced by half.

In addition, the device further includes a control unit (not shown in the drawing) that controls the needle assembly (200), RF generation unit, and vacuum pressure forming unit (500), and the control unit can control the needle to advance through the motor (210) while pulling the skin in contact with the skin contact unit (400) through the vacuum pressure forming unit (500), and to generate RF energy in the RF generation unit and apply it to the needle.

The above control unit can control all processes of inserting and removing the needle and applying RF energy. First, in order to recognize that the skin contact portion (400) has come into contact with the skin, a sensor for detecting whether the skin has come into contact with the skin can be installed on one side of the surface of the skin contact portion (400). The control unit, which has received a signal that it has come into contact, forms vacuum pressure through the vacuum pressure forming portion (500) to pull the skin that has come into contact with the skin contact portion (400), and while the skin is pulled, the needle advances by the motor (210) and penetrates the needle case (230) to be inserted into the skin. Thereafter, RF energy is applied to the needle inserted into the skin, and after the process is completed, the needle is returned to its original position and initialized.

Here, when vacuum pressure is formed in the skin contact portion (400) from the vacuum pressure forming portion (500), the motor (210) can be used to advance the needle only when the skin is in contact with the entire area of the skin contact portion (400), and the RF generating portion can be controlled to apply RF energy to the needle. Since some areas of the skin contact portion (400) are connected to the suction tube (520), the needle may be inserted without sufficient vacuum pressure being formed in all areas of the skin contact portion (400), and thus there is a possibility that not all needles may be inserted accurately. In order to prevent this, the motor (210) and the RF generating portion can be controlled to proceed with the subsequent process only when the entire area of the skin contact portion (400) is in contact with the skin through a configuration of a sensor, etc. installed on one surface of the skin contact portion (400), thereby increasing accuracy and efficiency.

The entire processor is described in more detail in Figure 5.

Referring to FIG. 5, in step a, the needle assembly (200) is pressed against the skin, and then in step b, the skin is pulled against the skin by a vacuum pressure forming unit (500), and in step c, the needle is inserted into the skin by a motor (210) from the needle assembly (200) to a preset depth, and in step d, RF energy is applied to the needle under the control of the control unit. Finally, in step e, the needle is returned to its original position to complete the process.

Although the present invention has been described above with reference to preferred embodiments thereof, it will be understood by those skilled in the art or having ordinary knowledge in the art that various modifications and changes may be made to the present invention without departing from the spirit and technical scope of the present invention as set forth in the claims below. Accordingly, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
